I see no justification for anything in this article. His assumption that beings like us (ability to reason about our place in the universe and even leave our own planet's gravity well) are common is dubious. There is no evidence of that at all.

I think the argument is this: given N beings in the universe that want to search for other such beings, if each being assumes they are the median it maximizes the chance that one being finds another. So maybe we are actually the 99th percentile in size, then it's okay that we are looking for larger beings, because the vast majority of beings that really are around the 50th percentile will be looking for larger beings.

Yes I want to believe this but, I'm afraid there is no science behind it. Based on # of galaxies and stars it does seem logical however, what unknown variables also equate into determining this? Needless to say I stopped reading after this assumption in the first paragraph.
